TC ALL WHOM IT MAYy GCN CERN Be it known that we, CHARLES VOGTand XAVIERKRAPF, both of Allentown, in the county of Lehigh, and in the State ofPennsylvania, have invented a new and useful Improvement in Constructingand Operating Churns; and we hereby declare that the following is afull, clear, and exact description thereof, which will enable thoseskilledin the art to malte and use the same, reference being hadto-theaccompanying drawing, forming part of this speciflcation, in whichdrawing- Fg-ure l represents a sectional side elevation of thisinvention.

Figure 2 is a plan or top-view of the same. l

Figure 4 is a modification of this invention, showing its application toa common dasher-churn.

Similar letters of reference indicate corresponding parts. I

This invention relates to a churn, which is operated by the action of avspring or weight power, of the spring o'r weight being controlled andregulated by an adjustable roller or friction-brake in such that a.uniform motion of the churn-barrel is obtained, and. the operation ofchurning,

the action a manner by the aid of spring or weight power, and itisprovided Witha lid, which is held at one end by an adjustable hinge, andat the other end by a cam-shapedclamp, in such a manner that, by meansof said hinge and, clamp, any change caused by shrinkage or expansion ofthe Wood canbea-compensated, and the lid -can always bereadily adjustedto close tight and to prevent any loss of cream by leakage.

4 A represents' a, frame, made of iron or any other suitable materialcapable of forming substantial lbearings for the shaft B, Aon which thebarrel C of the churn is mounted. 0n the shaft B is also mounted apinion, a, which connects by asuitable train of gear-wheels with themain wheel b, to which motion is imparted by the action of a spring orweight. The motion ofthe shaft B is controlled by a brake, lD, whichconsists of a hinged strap, carrying a frictionroller, which can be madeto bear with more or less force against a drum, c, mounted on the shaftB, a thumb-screw, d, being provided which serves -to regulate the forceof thebrake. By this dasher attached to it, and the' churning, jbyspring or weight power, is rendered practicable, whereas, without theadjustable brake, the motion produced by the spring or weight power isnot uniform, being too fast at one time, so as to cause a splashing ofthe cream, or too slow at another time for the success or rapid progressof the churning operation; and, furthermore, the spring or weight power,having its motion regulated,- will run much longer than it will if itsmotion islnot controlled. The barrel C, which I use in preference to anordinary flasher-churn, is mounted on the shaft C, and it is providedwith a lid, e, which is connected to the bodyf of the barrel by a hinge,g, onehalf of which is rigidly attached to the lid of the barrel, whileits other half Ais made adjustable `by means of a screw, It, whichpasses through a bracket, z', and is tapped into a lug rising from vthatpart of the hinge which is connected to thc body of the barrel, so that,if the wood of thc barrel shrinks, by

turning the screw L the-lid can 'be' drawn up tight against the body; orif the wood swells, the hinge can be released, and injury to the barrelcan be prevented. The lid is locked by a cam-shaped clamp, j, whichcatches overtwo studs lf: Z, one of which is rmlyattached to the lid,and the other to the body of the barrel, The clamp consists of an ovalor cam-shaped ring, provided with a lever handle, and sol arranged thatthe same, when turned in one direction, can be readily dropped over thestuds vc Z, and after it has been dropped over these studs, by turningthe lever-handle, the lid is drawn up tight against the barrel, andanyloss of cream by leakageduring the operation of the churn can bereadily prevented.

What we claim as new, and desire to secure by Letters Patent, is

The'arrangement and combination of the churn-barrel C, adjustable hingeg, cam-shaped clamp j, adjust. able brake D, and driving-shaft B, allconstructed and 'operating substantially as and for the purpose Setforth.
